This type of shirt was worn in the 18th century well into the 19th century. They buttoned at the neck with a  slit till about mid chest and at the wrist . These shirts were made like a jigsaw with plenty of gussets, rectangles and curved sleeves. These shirts were made not only to wear as a day to day item but many were also used as night shirts. These shirts are made of a light weight cotton. Great for a man's work shirt.
